J. A. BUGKWALTER, OF KIMBERTON, PENNSYLVANIA.

BRICK-MOLD.

Specification of Letters Patent No. 25,626, dated October 4, 1859.

To all whom it may concern:

Be it known that I, J. A. BUCKWALTER, of Kiinberton, in the county ofChester and State of Pennsylvania, have invented a new and usefulImprovement in Brick-Molds; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the annexed drawings, making a part of this specication, in which-Figure l is a plan or top view of my invention. Fig. 2 is a side view ofthe same partially bisected. Fig. 3 is a side sectional view of thesame, taken in the line A B, Fig. 1. Fig. t is a transverse section ofthe same, taken in the line C D, Fig. l.

Similar letters of reference indicate corresponding parts in the severalfigures.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A represents a frame constructed ofv wood, or metal, of skeleton formand quadrilateral. This frame has inclined pendants, cl, attached to theinner surfaces of its sides, and extending down, atequal distancesapart, in line with the partition plates, c, which willpresently bedescribed. The upper parts of the pendants, cl, except the end ones, areconnected by traverse bars, M, and the lower parts are connected bytraverse bars, N. The upper surface of the frame, A, is formed oftraverse strips, a, attached to longitudinal bars, E E, the latter beingsecured at their ends to the end pieces of the frame, A, and the sidesof the frame are formed of sla-ts, L, and longitudinal bars, H and theinner surfaces of the slats, L, are inclined, as shown in Fig. 4. Thependants, CZ, are groovcd or recessed at their inner or face sides so asto form a projecting flanch, cZ, at each side. In addition to the slats,L, the sides of the frame, A, are provided with inclined slats, L, theinclination of the latter' corresponding with the inclination of theinner surfaces of the slats, L.

B represents what may be termed an expanding frame. It is formed ofplates, o, which are placed one at each side of the several bars, M N,and said plates have pins,

'bearing against the inclined pendants, CZ

7', attached, which are fitted in the recesses of the pendants, d, (seeFig. 3). The ends of the plates, c, at their lower parts have each asmall guide strip, 7c, attached, which strips work underneath guidestrips, h, attached to bar, b', which bars have each plates, 75k,attached, some or all of which are provided with staples, g, which claspor encompass the inclined slats, L. The strips, le, of plates, c, areallowed to slide freely underneath the strips, it.

b are end pieces which have each a plate, c, attached; said plates, c,passing upward within the end pieces of the frame, A, and

5 the plates, o, being also provided with pins, f, which iit into therecesses of their pendants. The lower parts of the plates, c, are alsoprovided with strips, lo, which fit underneath strips, 7L, on the bars,b.

From the above description it will be seen that the plates, c c and formthe molds which work within the frame, A. lVhen the plates, c c and if,are within the frame, A', the molds receive the clay, and the clay iscompressed therein by the followers, when said plates are within theframe. Vhen the clay is fully compressed the frame, A, is raised and theplates, o c if, are expanded and the capacity of the molds areincreased, so that the molded clay may be readily discharged.

This improvement may be arranged in any proper way so as to be operatedautomatically in connection with followers.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is

rThe expanding frame, B, formed of the movable plates, c c if, andfitted within the frame, A', provided with the inclined or taperpendants, (Z, and inclined slats, L L', the plates, c c if, beingconnected respectively to the pendants, d, and slats, L', by the pins,7L', and staples, g, substantially as and for the purpose set forth.

J. A. BUCKVALTER.
